I am using OctoPrints plugin 'GPIO Shutdown', for that a separate button is used to turn off OctoPrint.
Since the Raspberry Pi (3B+) is fixed to the frame of my printer and I didn't want a loose swinging button, I made a frame that is clamped between the GPIO header and the HDMI output of Malolo's enclosure. The first and last 6 GPIO rows are still free to use.
Inside the holder is a 'tactile switch', in front of the switch an extra printed button. The button and bracket are sufficiently secure.
The PCB needs supports, I have turned off the supports inside the GPIO header.
Please note: the photos do not reflect the exact quality of the design, the first layers did not come out of the printer very well. I will photograph and upload a better print in due course.
